Averaging and persistence on the oscilloscope. A DISPLAY row of three keys - NORM, AVG and PERSIST. AVG settles the FM multiplex (or any spectrum) into a steady picture in which the pilot and subcarriers stand clear; PERSIST keeps an amber max-hold over the spectra and a fading memory of the trace on the waveforms and the vector display.
Trail width, up to the aircraft's wingspan. VIEW > Display > Trail width, also beside the map's Line/Ribbon choice. 4 px as standard (the old line was 1.5 px), on the maps and the radar scope.
Light helicopters. When the optional aircraft-registry plugin knows a helicopter's type, a single-engine helicopter (Robinson, Bell 206/407/505, AS350/H125, EC120/EC130 and others) draws as a small two-blade helicopter.
Fixes: the multiplex view now greys out TIME and GAIN like the audio spectrum does, and the scope's settings are saved as soon as they change.
